Professor Macfarlan is First Author of a New Study with Napoleon Chagnon about the
Yanomamö

Professor Shane Macfarlan is first author of a new study with provocative anthropologist
Napoleon Chagnon about the Yanomamö:

"When Yanomamö men in the Amazon raided villages and killed decades ago, they formed
alliances with men in other villages rather than just with close kin like chimpanzees
do. And the spoils of war came from marrying their allies' sisters and daughters,
rather than taking their victims' land and women."
